Supramolecular aggregation—driven by weak non-covalent interactions, such as van der Waals, π–π interactions, hydrogen bonding, and electrostatic—has been utilized to build sensing platforms with improved selectivity and sensitivity. Supramolecular aggregates, owing to cooperative interactions, higher sensitivity and selectivity, relatively weak and dynamic non-covalent interactions, and environmental adaptation, have achieved better sensing performance than that of molecular sensory systems that rely on sensors with delicate structures. Aggregation of Luminophores in Supramolecular System: From Mechanisms to Applications describes recent advances in supramolecular chemistry, in which the luminophores are almost non-luminescent in the molecular state, but become highly emissive in the aggregate state. These advances bring new opportunities and challenges for the development of supramolecular chemistry. The intermolecular non-covalent interactions have been considered to be the main driving forces for fabricating supramolecular systems with aggregating luminophores and have an important influence on the luminescence properties of the probes. Based on these unique properties, luminescent supramolecular aggregates have greatly promoted the development of novel materials for applications as sensors, bio-imaging agents, organic electronic devices, and in the field of drug delivery. Features: Discussion of fundamental and interdisciplinary aspects of the aggregation in supramolecular systems. Narration of intermolecular interactions and the photophysical phenomenon of aggregation in supramolecular systems. Comparative discussion on recent developments in aggregation-induced quenching (AIQ) and aggregation-induced emission (AIE), and drawbacks of AIQ. Description of the technological applications of aggregation as biological sensors, chemical sensors, organic electronic materials, and in the field of drug delivery. A convenient format for checking formulas and definitions. This book surveys highlights of the progress made in the field of the aggregation of luminophores in supramolecular chemistry. It is hoped that the work will form a foundation (and indeed a motivation) for new workers in the area, as well as also being useful to experienced supramolecular chemists. It may also aid workers in the biological area to see Nature’s aggregation in a new light. Further, the approach employed has been designed to provide readable background material for use with graduates, senior undergraduates, research professionals, and industries.

Multidisciplinary coverage of circular dichroism's principles, applications, and latest advances The four years since the publication of the first edition of Circular Dichroism: Principles and Applications have seen a rapid expansion of the field, including new applications, improved understanding of principles, and a growing interest in circular dichroism (CD) among researchers from a wide variety of disciplines. The Second Edition keeps pace with this phenomenal growth with up-to-date contributions from dozens of the world's leading researchers and practitioners in chirality, chemistry, biochemistry, and analytical chemistry, as well as vibrational and luminescence spectroscopy. With nine entirely new chapters and substantial updates of existing material, Circular Dichroism, Second Edition provides important insight into the immense potential of CD and bridges the gap between theory and practice. The book begins with coverage of historical developments and moves quickly to fascinating reports on recent advances and emerging new fields in CD. New and updated coverage includes: * VOA theory * Solid-state CD applications * Fast time-resolved CD measurements * A model illustrating how polymers amplify chirality * Induced CD of polymers * CD of nucleic acids: nonclassical conformations and modified oligonucleotides * DNA-drug and DNA-protein interactions * Applications of CD to important pharmaceutical compounds Featuring an increased emphasis on biological molecules and extensive applications to organic stereochemistry and biopolymers, Circular Dichroism: Principles and Applications, Second Edition will prove a valuable and frequently consulted reference for organic chemists, biochemists, and medicinal and pharmaceutical chemists.

The aim of this book is to provide an introduction to all those who wish to use the complementary spectroscopic techniques of optical activity (circular dichroism, CD) and optical anisotropy (linear dichroism, LD) for the study of the structure of molecules and interactions between molecules in solution. The emphasis of the book is on what the techniques are and how to use them for both low and high molecular weight molecules. It is intended to be an easy guide to what a prospective user of CD needs to know and explains how LD is not merely an exotic technique only to be practised by experienced spectroscopists, but may be routinely and usefully employed as an aid to molecular structure determination. This book begins by describing the principles behind CD and LD and how these techniques can be used in the laboratory without using advanced maths or quantum mechanics. The next chapters describe how both techniques may be applied to the study of biological macromolecules and give a detailed description of how they may be used on small molecules to investigate molecular and electronic structure. The final part contains theoretical derivations of all the equations required for the applications described previously. Throughout the book specific molecular examples are used to illustrate concepts and to show the reader how to use the techniques in chemical and biological systems. Circular Dichroism and Linear Dichroism is the first book that is an easy, directly applicable manual to the use and interpretation of both CD and LD. It will be of use to both novices and experienced researchers in the field.
